We characterize the notion of a triangulation, in which every vertex has a star-neighbourhood, in terms
of an internal categorical structure. This structure is important since it allows to have more efficient and robust
algorithms that can be used in additive manufacturing.
This short review aims to look at some of the applications based on potential pine associated resin (rosin)
composites for cell culture studies via hydrogel fabrication. Although hitherto there are only a few links to pine resin based hydrogel formation in the public domain, literature work based rosin incorporated drug delivery studies and its associated uses can be useful for extensive works on the cell interaction and viability. Rosin in such case may be optimised to afford similar characteristics hence applications.

Deciding about which coding sequences should be used is an important issue in many communication
systems, such as those employing Code Division Multiple Access (CDMA). In this paper, we propose a cascading electronic codec based on a recursive algorithm for the generation of perfect sequences, derived from an Inverse Discrete Fourier Transform (IDFT) of Golay codes. The sequences generated have a low Peak-to-Average Power Ratio (PAPR), around 3 dB, which is the PAPR of a sine wave. The proposal is compared to the original Golay codes, verifying that our codec provides better crosscorrelation and autocorrelation results, crucial to gain immunity to...

Silk hydrogels have been highlighted in the past decade as potential matrices for tissue engineering and
regenerative medicine applications. In this mini review, the biological attributes of silk proteins, as well as methods
reported in literature to fabricate silk hydrogels will be discussed.
